The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00095 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

要約

The purpose of this study is to investigate the spray plume shape and fuel atomization characteristics of a gasoline direct injection (GDI) system. The spray characteristics were analyzed according to ambient gas pressure, temperature and injection pressure. The multi-hole type GDI system was simulated to enhance the fuel atomization performance. A multi-dimensional computational fluid dynamics code (KIVA-3V) was implemented to predict the two-dimensional spray behavior. The predicted spray penetration, velocity distribution of ambient gas, droplet size and spray plume shape results were compared with the experimental results to verify the accuracy of numerical models. The Kelvin−Helmholtz, Rayleigh−Taylor breakup model and radius-of-influence collision model were applied for the prediction of spray behavior and characteristics. It was found that the ambient gas pressure had a significant influence on spray tip penetration length and spray plume shape. In addition, the Sauter mean diameter was decreased and vortex became stronger with higher injection pressure. On the whole, the present calculation models showed good agreement with experiments in terms of spray shape and size distributions.
